I am trying to unpack a pp file obtained from BADC using the fortran script 'unppack.F' that they supply for WDGOS archive unpacking.

My machine is a Linux x86 m32

The header record of the pp file is correctly being read in, however when i am reading in the packed data field with the following line,

READ(ICHAN,END=2000) (IDATA(JD),JD=1,NIN)

I obtain the following error message.

do_us: off end of record
apparent state: unit 11 named ukmo-nwp-strat_gbl-std_2006030412_u-v-gph-t-w.pp
last format: list io
lately reading sequential unformatted external IO
Abort

Can some-one tell me what this error message means
Any help would be greatly recieved. dl226
